Professor Justin Kruger's joint research on self-perception is referenced
— March 9, 2017
Excerpt from Business Insider -- "This overestimation is called the Dunning-Kruger effect. It is the cognitive bias that makes less competent people overestimate their own skills while underestimating the competence of others. The term was coined in 1999 in the publication of David Dunning and Justin Kruger. The psychologists had noticed in prior studies that in areas like reading comprehension, playing chess or driving a car, ignorance leads to confidence more often than knowledge does."
